To all whom it may concern: I

Be it known that I, AnoLr BAYER, a subject of the Emperor ofAustria-Hungary, applicant for citizenship of the United States, residing at Brooklyn, in the county of Kings and State of New York, ha've invented certain new and useful Improvements in Revolving-Piston Explosive-Engines, of which the following is a specification.

M'y invention relates to revolving piston explosive engines, and its object is to produce an internal combustion consuming gasolene spray or gas, and having parts of special construction and particular arrangement whereby it is believed that greater economy of construction is attained, and the necessary parts are reduced to a minimum number and weight with reference to the power given out bythe engine in regular service. I

I accomplish the stated object by fashioning and associating the constituent elements substantially as illustrated in the accompanying drawings, of which Figure 1 represents a side view. Fig. 2 is a vertical, longitudinal section, Fig. 3 is a horizontal longitudinal section of the pump cylinder and piston casing, the l other parts being shown mainly in full lines.

Like reference numbers are used to denote the same parts throughout the specification and claims.

Upon a suitable bedplate 1, is supported the cylinder casing, which comprises the annular frame 2, and the circular side plates 3 and 4. The side plates are provided with bearings 5 and 6 for the transverse engine shaft 7. The revolving cylindrical piston 8 is secured eccentrically upon the shaft 7 within'the casing, as illustrated in Fig. 2. 1

The frame 2 of the casing is provided with 'an inwardly-opening sir valve 9 by way of which external air may enter the casing, and an outwardly-opening exhaust valve 10, both of those valves being again referred to in this description, I

To comprem and supply the explosive mixture to the engine, I construct the pump cylinder 11, which is secured to. the piston casing and projects radially and horizontally from the frame 2 as shown in 1 and 2.

His my practice, usually, tosupport the pump cylinder uponthe bedplate by means of the 12.

Within the pump cylinder is the pump piston 13,- and the piston rod 14 through the pump piston and through the head of the pump cylinder to the outside in one direction, and in the other direction the rod extends through the guide bearing15, and into the throat 16 forming part of frame 2. I From Figs. 2 and 3,

it will belearned, that the end of the piston rod is bored axially to receive movably the extension rod 17. At

its outer end theextension rod is secured to a cross head 18, and encircling the extension rod between the 'crossheada'nd the endof piston 14 is a helical spring .19. The crosshead bears the suitably mounted trans- 'as little friction as possible by reason of such contact,

f order to close the I:

-.3 guided in the bearings 40, 41 and 42. The companion llt verse roller 20, which is kept normally in contact with the revolving piston 8. The ofiice of the roller is, while in constant contact with the revolving piston, to cause introducing rolling rather than sliding friction. The office of the spring 19 is to extend the movable rod 17 and the cross'head into contact with the revolving piston when, as is the case at the beginning of the movement, the revolving piston leaves the socket or seat 20 in frame 2 faster than piston rod 14 is drawn towards the left by the side bars operated by the disks and rollers hereinafter described.

To keep the crosshead always in the same position with respect to its socket or seat in order that it may enter the same truly each time it returns from its excursion into the casing, I provide the two guide rods 21 and 22 as best shown in Fig. 3, one upon each side of the piston rod. The guide rods have one end secured to the crosshead and pass outwardly through the bearings 23 and 24 formed in frame 2.

.The head of the pumpcylinder is provided with the hood 25, that covers the suction valve 26 and the inlet valve 27 by way of which the gasolene or gas enters and is explosively mixed with air drawn in through the perforations 28 shownin the end of the hood. The head of the pump cylinder also carries a second hood 29 which possesses a lateral extension 30, and also covare an outwardly-opening valve 31. When the valve 31 opens, by reason of internal pressure, the pump cylinder is in communication by way of the extension 30 of thp hood with passage 32 formed lengthwise'in the upper wall of the cylinder 11, and leading to and opening into the port 33 in the frame 2 of the'casing of the revolving piston, and through which the exploded gases reach the-piston and actuate it. It is my practice to control the passage 32 by means of a cut-off v alve 34 located near the port 33. This valve is necessary in e while the explosive are being compressed therein as" hereinafter set forth. Valve 34 is operated by'raising and lowering it, and those movements are efiec ted by means of the curved arm 35, one end of which is pivotally connected with the valve 34 and the other end is pivotally secured to the circular side plate 5 as shown in Fig. 1. The arm 10. 35 is provided with an enlarged portion or cam 36 hav-, ing curved surfaces leading to it and fromit as indicated, and it is arranged to be encountered by a like enlargement 37 formed upon the link frame portion 38 oi'the sliding side-bar 39, as best shown in Fig. 1. Y There are two sliding side-bars, arranged horizontally lengthwisenear the pump cylinder and casing 2, one on either side thereof as shown in Fig. 3. Side-bar y mentioned, is moi/ably supported and side-bar on the other side, as best shown in Fig. 3, is marked 43, and its bearings are referred to by the numthe air, the pressure bcrs 44, and 46. One end of each of the side-bars 39 and 43 is secured rigidly to the transverse end bar 47, best. shown in Fig. 3, and to the end bar 47 the piston rod 14 is likewise connected. The side-bars are movable as indicated lengthwise in two directions. Towards the left hand they are moved by the action of the disks 48 and 49 both iixed upon the outer ends of the engine shaft 7, the disks engaging the rollers 50 and 51 shown in Figs 1 and 3 as 'rotatably-bome by the side-bars in contiguity with the disks. Towards the right, the sidebars are carried by the movement of the piston rod 14 with which they are connected as already explained.

The operation of my invention may be described as follows: The flywheel 52 being suitably rotated by hand or otherwise, a charge of the explosive mixture is drawn into the pump cylinder by way of the valves 26 and .27, and the return of the piston 13 compresses the gaseous body into the passage 32. Atthe same .time, the two cams or enlargements 36 and 37 upon the pivoted arm 35 and side-bar 39 come into contact, with the result that'- the valve 34 israised quickly, and the spring lingers 53 and Marc separated. breaking the circuit from the battery 55, and, by the agency .of a spark coil 56, a spark is generatedat the spark plug 57 and the gaseous charge exploded. The products of the explosion rushes through the port 33 in the frame 2 and acts upon the revolving piston 8, which is forced in the direction of the arrow. 3 Thehot gases continue as they expand to press and drive the-piston 8 until the force of the; explosion is exhausted, and as the piston continues its movcment the expanded gases are forced out by way of the exhaust valve. As the piston 8 leaves the position shown in Fig. 2, it begins to draw away from the port 33, and the force of the explosion driving the gases through the port 33 would shoot at least a portion past the piston thus wasting its effort. But, as the piston 8 revolves, as has been explained, the engagement of thedisks, and the rollers 50, 51, on the side bars acting through the piston rod keep the extensible crosshead I in contact with the revolying piston. lly this constructit-in the gases are temporarily confined between the frame and revolving piston immediately above the crosshead 18, and their pressure exerted in-usefil effect upon the piston until they. have fully expailded. As the movement continues,"a new charge is drawn into the pump cylinder and compressed by the pump piston 13 under the impulse stored up in the revolution of the flywheel, 'and, as will be understood, an explosion takes place for each revolution of. the engine shaft. After the engine is shut down, if by reason of internal condensation the pressure within the cylinder casing drops below that of valve 9.
